UNITED STATES ARTHUR B. MODINE, OF RACINE, WISCONSIN.

AUXILIARY LIQUID-STORAGE RECEPTACLE FOR A CIRCULATING SYSTEM.

Application filed December 29, 1919. Serial No. 348,241.

To aZZ whom it may concern:

Be it known that I, ARTHUR B. MODINE, a citizen of the United States, residin at Racine, in the county of Racine and tate of Wisconsin, have invented certain new and useful Improvements in an Auxiliary Liquid-Stora e Receptacle for a Circulating System, of which the following is a description.

My invention relates to means for removing the circulating liquid from a, cooling system and storing the same when the system is not in service and for returning the liquid to the system when it is desirou to operate the system.

The object of my invention is to provide a simple, convenient, reliable and inexpensive device of the kind described wherein an insulated storage receptacle is provided adapted to maintain the temperature of the circulating liquid when the same is in the receptacle.

To this end'my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts:

Fig. 1 is a side elevation of my improvement as applied to an automobile with parts removed and broken away to more clearly show the construction.

2 is an end elevation of the same.

Fig. 3 is a view similar to F i 1 but showin a slightly modified form 0 my de- Fig. 4 is an enlarged sectional detailed view of a portion of the mechanism shown in Fig. 3.

Fig. 5 is a section taken substantially on line 5-5 of Fig. 4.

In the drawings for the urpose of illustration 1 is an internal com ustion motor of the usual or any preferred form provided with an intake manifold 2 and an exhaust manifold 3,-a radiator 4 is also provided and connected by pipes 5 and 6 to the water jacket of the motor and forming with the water jacket the circulating system for controllin the temperature of the motor all forme and arranged in substantially the usual or any preferred manner.

As shown a receptacle 7 is positioned above the circulating system and connected to the upper part of the radiator 4 by a duct 8 or other suitable means arranged to per mit the liquid in the receptacle to drain lnto the system. A valve 9 or other convenient means is positioned in the receptacle and arranged to close the duct 8 when desired to prevent the passage of fluid from the receptacle into the system.

Any suitable means may be provided to control the position of the valve 9. As shown a yoke 10 is rigidly secured to the bottom of the receptacle and a spring 11 is provided within the yoke arranged to normally maintain the valve in its closed position. The valve stem 12 extends upward through a suitable bearing in the yoke and 1s suitabl connected to the free end of the arm 14 o the bell-crank lever 14-15 pivotally mounted upon the Wall of the receptacle as at 16. A rod 17 is connected to the free end of the arm 15 of the bell-crank 14-45 and extends through a suitable gland or stufiing box 18 in the wall of the receptacle to prevent the leakage of liquid around the rod so that by movin the rod 17 longitudinally the valve 9 may manually opened or closed as desired.

A tubular passage 19 extends from the lowest portion of the system to the upper portion of the receptacle 7 and a vent 20 is provided extending from the filling nozzle 21 upon the receptacle outward adapted to operate as an overflow when filling the receptacle and also for the escape of air from the receptacle. Any suitable-means may be provided for moving the liquid in the system into the receptacle. As shown a small pressure tank 22 is provided and connected to the pipe 5 by a suitable passage 23 and to the exhaust manifold 2 of the motor 1 by a pipe 24 provided with a valve or cook 25 for controlling the movement of the fluid through the pipe. When thus constructed if the valve 9 is closed and the cock 25 its open pressure from the exhaust manifold 2 is admitted to the pressure tank 22 thence through the passage 23 into the pipe 5 forein the liquid from the system through the tu ular channel 19 into the receptaclethereby completely draining the system of liquid and placin the liquid in the receptacle including alfiiquid which might have been in the tubular channel 19 thus preventing the possibility of any liquid freezing in any portion of the system or in any way interfering with its free operation. The receptacle 7 is preferably provided with a covering 26 of heat insulating material so as to maintain the temperature of the liquid in the receptacle for a considerable period even in very cold weather. When it is again desired to operate the motor the rod 17 is moved to open the valve 9 thus permitting the liquid in the receptacle to return to the circulating system. Obviously if desired the receptacle 7 may also be employed for the storage of a reserve supply of liquid or if preferred may be made apart of the circulating system; when this is desired a passage 27 is preferably provided from the pipe 5 to a suitable point in the receptacle with a closure 28 provided therein so that by opening the closure 28 and substantially filling the system and receptacle with liquid the circulating fluid in the system will pass upward'through the pipe 27 into the temp tacle thence downward through the radiator in the usual manner thereby making the receptacle a part of the circulating system. 'When it is desired however, as in cold weather to use the receptacle for the storage of the liquid normally in the system the closure 28 is closed and the quantity reduced to conform to the capacity of the receptacle.

In the form shown in Figs. 3, 4 and 5 the several arts are constructed and arranged substantially as hereinbefore described, except that in this case the valve-stem 30 corresponding to the valve-stem 12 is extended .upward and provided with a longitudinally movable sleeve 31 having an arm 32 extending laterally therefrom and provided with a. valve 33 adapted to close the upper end of the vent 20. A spring 34 or other resilient means is provlded to normally hold the sleeve 32 at the lower limit of its movement and insure the proper seating of the valve 33 and 9 when the rod 17 is operated to close the valve 9. In this form also the "small pressure tank 22 and associated parts are omitted and a pipe 35 extends from the intake manifold 2 of the motor to the upper portion of the receptacle 7 and a valve or cook 36 is provided to control the move ment of fluid through the pipe 35. In this form of my device a vent 37 is also preferably provided in the duct 8. with suitable means, as the closure 38, for closing the vent when desired. When thus constructed, if the valve 9 and closure 28 are closed and the valve 38 and cook 36 are opened with the motor in operation, the partial vacuum in the intake manifold 2 will be communieated to the receptacle 7 causing the liquid in the system to flow from the system into the receptacle through the tubular channel 19 where the liquid may be stored as hereinbefore described and returned to the system when desired by opening the valve 9 and preferably closing the closure 38. The mechanism operating in all other respects substantially as hereinbefore set forth.

Having thus described my improvement it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form or construction shown.
